To all whom it may concern Be it known that 1, Earn R. DRAVER, a citizen of the United States, residing at liichmond, in the county of Wayne and State of lE/iinnesota, have invented certain new and useful Improvements in Feed-Regulators; and i do hereby declare the follow- 7 ing to be full, clear, and enactdescription the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to feed regulators and in the nature of an improvement on the feed regulator disclosed and claimed in prior Patent 1,307,349 of date, June Generally stated, the invention consist of the novel devices and combinations of devices, hereinafter described and defined in the claim. 7

Feed devices of the character herein considered are especially adapted for use in gangs, to commingle-or blendfogether, various ditlerent materials, such for example, as different grades or kinds of flour or different kinds or grades of grains or cereal products. v v

The present invention is illustrated in the accompanying drawings, wherein like charaeters indicate like parts throughout the several views.

Referrin to the drawings:

Figure l is a side elevation of the im proved feeder or feed regulator;

Fig. is a front elevation of the feed regu: ome parts being broken away; 3 is a section taken on the line 33 i: is a view corresponding to Fig. 2-, illustrating the somewhat modified form of: certain of the elements, and some parts being broken away; and

Fig. 5 is a perspective view showing one construction of the drum elements 0L the illustrated in Fig. el. 7

T he material is fed through a casing made of sheet metal plates 6 and 'Z and side plates 8-, which side plates are preferably cast and rigidly clamped to the plates 6 and 7, by suitable bolts 9. The casing thus formed has a large inlet passage 10 at its top, and at its bottom has a large discharge passage 11. The casing is shown as mounted on a floor or flat support 12.

Mounted to rotate within the casing, is a teed drum 13, the shaft l l or" which is journaled in and projects through suitable bearings on the side plate 8 of the casing. This drum is adapted to be rotated by any suitable means, but as shown, it is arranged to be rotated by the following devices:

A large ratchet wheel is secured on one projecting end ofthe drum shaft 14. Arms l6 are pivoted on the shaft 14 and provided with reversely acting ratchet dogs 17 that operate on the teeth of the ratchet wheel 15. The free ends of the arms 16 are pivoted to the ends of links 18, which links are connected by a common pivot 19 to a cross head 20 mounted to slide on an arm 21, which arm oscillates on a pivot 22. Oscillatory arm 21 is given its movement through a link 23 that connects the same to a driving crank 2 that is carried by one end of a driving shaft 25 ournaled in the side plates 8 and equipped with a pulley 26. The pivot 22 for arms 1, as shown in the form or" a shaft is mounted in suitable bearings on the ends of the side plates 8. v

The feed drum 1?) is provided with circun ierentially spaced pockets formed by end flanges or plates 2'? on the ends of the drums and longitudinal pocket-forming partition flanges 28 that are secured at their ends to said ending plates 27. The longitudinal flanges 28 extend obliquely in respect to planes that mediate from the axis of the drum and preferably they are spirally disposed and are parallel.

in the feeding action, the drum is arranged to rotate in a direction or the arrow, marked thereon in Fig. 3, so that the stock will be carried under the drum. The lower end of "the plate 6 is curved to form a portion 6 that approximately follows the lower portion of the outer-most partoff the drum and terminates at the oblique delivery edge 29. As highly important feature of this invention, the oblique delivery edge 29 is made oblique in a direction reverse from the trend of the drum flanges 28, (see particularly note 2, which shows the manner in which the oblique flanges 28 cross the oblique delivery edge 29.) Here it may be noted that the flanges 28 and delivery edge 29 are reversely oblique to such an extent 2 that the said oblique delivery edge 29, in

numerous positions to the drums will extend from the left-hand end of one flange 28 to the right-hand end of the adjacent flange 28.

This gives a Very deep pocketable or chamber formation around the drums between partition flanges 28 and Within or above: the extended bottom surfaced. The reverse obliquity of the partitions 28 and delivery edge 29 of the casing are very important for the above noted reasons that they afford deep pockets for holding material in the feeding action. Moreover, the materials from these pockets will be delivered or discharged progressively from one side of the drum toward the other,.so that the pockets will not dump stated, Figs. 4: and 5 show the drum made up of a plurality of sections, 13* having pro- 'ectin oartitions torinin blades 18 torined 3 e a p These drum with flanges 18* at one edge. sections are put together on shaft i l, so that their blades 1S Withfianges 18 form oblique longitudinal partitions that are serrated or stepped, as best shown in Fig. 4.

These reversely oblique relations of the longitudinal partitions of the drum or rotary feed elements and the edge of the delivery plate or portion ofthe casing, are

considered broadly new, and hence I desire to claim the same broadly.

' F or the feeding of flour and some other materials, I findthat the best results can be obtained by rotating the drum in a-direction t0 carrythe material under the drum in delivery action. WVith the drum arranged to deliver in this manner over the oblique delivery edge of the casing, the poekets'of the Y drurnare upside-down during the discharging action so that the material therein contained will'have the treest kind of discharge under the action of gravity. 7 This is espe.

cially advantageous when handling finely ground or fine materials, such as flour, .Wlnch \vill-have'a tendency to pack and stick and Which would not flow freely over the" upper edge of a pocket at the top of the drum. The eiliciency of the above device has been demonstrated in practice. V

What I claim is: i A feed device comprising a casing having inlet and discharge passages, and a drum 1'0 tatably mounted in said casing, said drum having pocket-forming longitudinal flanges and said casing havinga discharge edge adjacent to each discharge passage, said discharge edge and the longitudinal flanges of said drum being reversely oblique but at approximately the same angle to a plane that" radiates from theaxis of said drum."

In test-mom whereof I affix In si nature i I y b V p in presence of two Witnesses.
